Kimihiko Nakajima,Kimihiko Nakajima,Masami Ouchi,Kazuhiro Shimasaku,Yoshiaki Ono,Janice C. Lee,Janice C. Lee,Sebastien Foucaud,Chun Ly,Daniel A. Dale,Samir Salim,Rose Finn,Omar Almaini,Sadanori Okamura +13 more
TL;DR: In this paper, the average metallicity and star formation rate (SFR) of Lyα emitters (LAEs) measured from a large-area survey with three narrowband (NB) filters covering the Lyα, [O II]λ3727, and Hα+[N II] lines of LAEs at z = 2.2.

TL;DR: In this article , the Atacama Large Millimeter/submillimeter Array (ALMA) observations targeting CO(6−5) emission from three luminous Lyman-break galaxies (LBGs) at z spec = 6.0293−6.2037 were presented.

TL;DR: In this paper, the authors presented the Ly$\\alpha$ luminosity function (LF) derived from 34 Ly$-alpha$ emitters (LAEs) at $z=7.0$ on the sky of $3.1$ deg$^2, the largest sample compared to those in the literature obtained at a redshift of 6.5$.
